E92 2007 325iSE N53 (3.0 litre), manual, ED
Worst: urban/suburban commuting, winter 29mpg
Typical mixed driving: 35mpg - seems to get "stuck" on 35.7 for days on end
Best: m-way or uncongested A roads, but not in cold weather: 42mpg

These are not measured brim-to-brim, just from the onboard computer. Are fuel computers accurate or optimistic like speedometers? If accurate, makes me wonder why BMW are ditching the naturally-aspirated 6-cyl N53 for a 4-cyl turbo.
